pbd_durspec_moment function

Moments of duration of speciation under protracted birth-death model of diversification

pbd_durspec_moment computes the moments of the duration of speciation under the protracted speciation model for a given set of parameters

pbd_durspec_moment(
    pars,
    order
)

Arguments

• pars: Vector of parameters:

  pars[1] corresponds to b (= la_3 in Etienne & Rosindell R2012) = speciation initiation rate

  pars[2] corresponds to la_1 (= la_2 in Etienne & Rosindell 2012) = speciation completion rate

  pars[3] corresponds to mu_2 (= mu_i in ER2012) = extinction rate of incipient species

• order: order of the moment to compute (1 is first moment, giving the mean)

Returns

The moment of the duration of speciation
